The mechanism of activation of NK-cell IFN-gamma production by ligation of CD28.

abstract：:Natural killer (NK) cells express receptors that are specific for MHC class I molecules. These receptors play a crucial role in regulating the lytic and cytokine expression capabilities of NK cells. In humans, three distinct families of genes have been defined that encode for receptors of HLA class I molecules. The fi...
